Intel Launches M.2 and Larger Capacity 2.5″ SSD DC S3500 Models
Posted by :AdminPosted date : November 11, 2014In Tech0
Two years in the past Intel launched the DC S3500 and S3700 SSDs that marked as the corporate’s first really in-home SATA 6Gbps SSDs. At present Intel is including M.2 type issue to the S3500 lineup together with greater capability choices within the common 2.5″ measurement.
The unique S3500 got here in capacities starting from as small as 80GB to as much as 800GB, however with the growing demand for top density storage, Intel is including 1.2TB and 1.6TB choices. There isn’t a change in the Flash Translation Layer (FTL) design to accommadate the additional NAND nor are there some other firmware or hardware modifications, so the brand new fashions merely have extra NAND on the board.
The 1.2TB and 1.6TB fashions present greater randon write speeds, which is sensible given the extra NAND. Sometimes regular-state random write efficiency will increase with extra NAND because of elevated parallelism, though solely to a sure threshold since extra NAND additionally provides monitoring overhead. Within the case of the S3500, the 1.2TB mannequin seems to be the sweetspot by providing 18.5K random write IOPS, whereas the 1.6TB SKU drops that determine to 14.6K IOPS. Furthermore, write endurance scales almost linearly with the capability because the 1.2TB is rated at 660TB and the 1.6TB at 880TB, whereas the prevailing 600GB and 800GB fashions are rated at 330TB and 450TB respectively.
The M.2 model of the S3500 is among the first enterprise-class SSDs in M.2 type issue. Function clever the M.2 fashions are equal to their 2.5″ counterparts, which means that there’s full energy-loss safety, finish-to-finish knowledge safety and AES-256 encryption. The M.2 fashions are available M.2 2280 type issue and because of the area constraints, solely 80GB, 120GB and 340GB capacities can be found.
The M.2 fashions truly carry barely larger random write speeds in comparison with their 2.5″ counterparts, though that comes on the slight expense of random learn efficiency. Since there isn’t any metallic chassis to assist with warmth dissipation, the M.2 fashions are a bit extra uncovered to thermal throttling, though Intel assured that so long as there’s sufficient airflow within the system the drive ought to keep inside its working temperatures and not throttle itself.
At this stage M.2 hasn’t actually been adopted by the enterprise area but, however there’s a rising curiosity for it because of the area financial savings. Intel informed me that they’re in talks with a number of OEMs about integrating the M.2 S3500 to servers, however as of now the primary marketplace for the S3500 is embedded units. This consists of units like ATMs, slot machines and money registers, that are transitioning to SSDs to save lots of area and improve reliability. The S3500 is definitely a very good match for that phase with its enterprise-class function set, whereas most M.2 drives available on the market lack options like full energy-loss safety.
Whereas many shopper drives are promoting at under $zero.50/GB, the enterprise options and further validation improve the price of the S3500. At proper under the $1 per GB mark, the S3500 is, nevertheless, a fairly aggressive drive within the entry-degree enterprise phase.
